PUMP.

EWECIFICATION forming part of Letters Patent No. $11,923, dated May 18,1886.

A pplication filed October 20, 1885. Serial No.180,45l. (No model.)

To aZZ whom it may concern.-

Be it known that we, WALTER WV. LAING and SAMUEL S. HU'roHINs, citizensof the United States, residing at Paola, in the county of Miami andState of Kansas, have invented certain new and useful Improvements inPumps; and we do hereby declare the following to be a full, clear, andexact description of the inveution,which will enable others skilled' inthe art to which it appertaius tomake and use the same.

Our invention relates to pumps, the object being to provide improvedmeans for adjusting or varying the stroke of the piston as desired, oras circumstances may require.

With these ends in view the invention consists in the improvedconstruction and combinations of'parts hereinafter fully described, andpointed out in the claims.

In the drawings, Figure l is a perspective view of a pump embodying ourinvention. Fig. 2 is adetail sectional view. Fig. 3 is a sectional Viewon the line as m of Fig. 3.

Corresponding parts in the figures are denoted by the same letters ofreference.

Referring to the drawings, A represents the body of the pump, which ispreferably constructed of gaspipe, and is jointed at the point orconnection of the spout, the sections being connected bya collar, B,which is interiorly threaded at its ends, and which receives theexteriorly-threaded ends of the sections, and communicating with thepump through the collar is a spout, O.

D represents an air-chamber, which is also of gas-pipe, bypreference,and which connects with the collar B, said air-chamber havinga stop-cock, a, to regulate the supply of air. Formed integral with thecollar B is an em tension, E, which projects laterally from the collarat right angles thereto.

F represents the fulcrum for the handle, which fulcrum is of gas-pipe,and has screwed or otherwise detachably secured to its lower end asleeve, 6, having the ears or lugs,which fit over the end of theextension E,and are pivotally connected therewith by a bolt, 6.

G represents an eyebolt, the eye of which fits upon the body of the pumpnear the upper end thereof. The end of this belt, which isthreaded,passcs through an opening in the fulcrum F, and on said boltare thumb-nut c e,

which bear against opposite sides of the fulcrum, and permit its upperend to be adjusted to or from the body of the pump.

Removably secured upon the upper end of the fulcrum F is acasting, I,which is divided, as shown, and fulerumedin the divided end of saidcasting is a handle,'J. composed of two sections, J J the section Jbeing of metal, and the section J of wood. The metal section J isprovided with an elongated slot, f, arranged vertically with relation tothe handle, and fitting in said slot is a bolt, K, upon the upperthreaded end of whichis a nut, g,which bears against the upper side ofthe handle. Pivoted to the lower end of the bolt, which end extendsthrough and beyond the slot, are straps L, which are pivotally connectedat their lower ends with the upper end of the piston-rod. The object ofthe slot and bolt to which the piston-rod is connected through themedium of the straps is to allow the bolt to be adjusted in said slot,so that the piston-rod will at all times bein a perpendicular positionwith relation to the body of the pump.

By making the fulcrum and piston adjustable in the manner beforedescribed we are enabled to increase or diminish the length of thestroke, and thereby control the supply of water without the necessity ofrenewing or changing the pump-heads.

Having thus described our invention, we claim- 1. The combination, witha pump, of a fulcrum pivotally connected with the pump at its lower end,and connected adjustably with the pump near the upper end thereof, ahandle pivoted to the upper end of the fulcrum, a vertical slot in theinner end of the handle, a headed bolt fitted therein, a nut on thebolt, the piston-rod, and straps pivotally connecting the piston-rod andbolt, substantially as set forth.

2. The combination, with a pump having the bolt and'piston-rod,substantially as set forth.

3. The combination, with a pump having the extension projectingtherefrom, of a fulcrum pivoted to said extension, a threaded eyeboltconnected with the pump, and passing through the fulcrum, and thumb-nutson said bolt bearing against the opposite sides of the fulcrum, as setforth.

4. The combination, with a pump and a fulcrum'for the handle pivotallyconnected therewith, of an eyebolt connected with the pump and passingthrough the fulcrum, and the thumb-nuts on the bolt bearing against theinner and outer sides of the fulcrum, as set forth.

5. A pump comprising in its construction two sections having threadedends, a collar having interior threads to receive said ends,

and having an integral extension, a fulcrum 20 the handle, a boltadjustably fitted therein, 25

and straps pivotally connecting the bolt and the piston-rod,substantially as set forth.

In testimony whereof we affix our signatures in presence of twowitnesses.
